This invention relates to fountain pens understood that said invention is to be limand more particularly to a novel form of ited, not to the specific details herein set writing point or nib provided with a rotatforth, but only by the scope of the claim able writing element held therein in suitable manner.

Among the objects of the invention is a nib or writing point which permits the use of the pen on any kind of writing surface without scratching or hanging in the fibers thereof.

, Other objects will readily occur to those skilled in the art upon reference to the following description and the accompanying drawing in which a Fig. 1 is a side elevation of a portion of the nib.

lig. 2 is a section on line 2-2 of Fig. 2

Fig. 3 is an end viewthereof.

As indicated in the drawing, the pen may comprise a suitable conventional barrel having held in one end thereof, a tapering point portion over which may fit a suitable cap.

' The point portion will be tapered a rather which follows:

A fountain pen including a barrel having 55 a nib including a conical element having a duct therethru leading to the apex of the element, a writing element in the said apex and consisting of a pair of hemispherical portions with their flat sides adjacent each 60 other and rotatably mounted upon and retained in said apex by a common axle element, said writing element being in position to receive ink from said duct.
